Contact material and the high proportion alloy, tungsten copper (Cu 10%~40%) and tungsten silver alloy made by powder metallurgy have good electrical conductivity, thermal conductivity and wear resistance of copper and silver. Therefore, it becomes the important contact materials of working parts in manufacturing knife switch, circuit breaker, and spot welding electrode and so on. The high proportion alloy with 90%~95% of tungsten, 1%~6% of nickel, 1%~4% of copper and 5% of iron instead of copper alloy, they are used in the manufacture of gyroscope rotor, aircraft, balance hammer of control surface, radioactive isotope and radiation shield material basket etc..
Tungsten and tungsten wire, tungsten belt as electro vacuum lighting materials and various forging components are used for electronic tube production, radio electronics and X injection technology. Tungsten is the best material for incandescent filament and spiral wire. High working temperature (2200~2500 ℃)ensures the high luminous efficiency, and small evaporation rate ensures the long service life of the wire.
Tungsten wire is used in the manufacture of electronic oscillation tube direct heating cathode and anode, cathode of high voltage rectifier and heated cathode heater of various electronic equipments. Tungsten is also used for the X light pipe and the cathode of gas discharge tube, and contacts of radio devices and electrode of atomic hydrogen welding gun. Tungsten and tungsten wire are used as the heater of high temperature furnace (3000℃) . Tungsten heater works in hydrogen atmosphere, inert atmosphere or vacuum.
